Diagnostic studies of allergic gastroenteropathy Part 1. Application of phonoenterography in hypersensitivity of the gastrointestinal tract

Allergic gastroenteropathy has various gastrointestinal symptoms caused by allergic reactions in the gastrointestinal tract after oral ingestion of specific allergens, but no diagnostic examination has yet been established. To evaluate gastrointestinal motility as a method of diagnosing allergic gastroenteropathy, bowel sounds caused by oral ingestion of distilled water, sorbitol or allergens were recorded intermittently for up to 5 hours after oral administration tests and analyzed by pulse density program. The results showed that bowel sounds in many patients with allergic gastroenteropathy increased much more than that in normal subjects when sorbitol was ingested. The increase in bowel sounds was even more marked after oral ingestion of allergens compared to that after distilled water. These data suggest that phonoenterography after ingestion of sorbitol is useful in screening for allergic gastroenteropathy, and also using this method with ingestion of specific allergens is effective for confirming the diagnosis of this disease.
